Huge problem with ESP on a wet track day, please help!
Went on a track day last weekend and the rain was poring down through the whole day.
The Pirelli Corsa system tires are not made for rain, I know that (basically four rear tires, Porsche/Ferrari have different Corsa front tires ) anyway I have an quattro RS4 so no problem running with slippery tires in the wet I just turn the ESP full off and drive wide drifting lines, right?
NOOOOOOO!
I turned the ESP full off, I know that the fist stage is ASP off, ESP on - blinking icon and the second stage is ASP off, ESP off - solid icon. After that nothing should stop the car from "drifting" ??
That was the problem every time when I tried to take a corner really wide and kick the back out, the ESP system locked the brakes like when the ESP is on or off in the first stage.
I felt that the ESP system came back on when one/some off the tires lost all the grip, is that the way it should work or is something wrong with my car??
If so, is there a way to totally kill the ESP but still have the ABS brakes? (not polling the ESP/ABS fuse)

yes ELEVENS, but in wet conditions when
one or two wheels completely loses grip the ESP comes back on, same ting on snow, slide ok, drifting ok, but when the wheels loses grip in an slide then BANG ESP back on. Have you tried that?

Fairly good, better grip then any "street tire" ...
and they last longer then an "full R tire"
>> But don't buy them for street if you want to drive safe in rain!!<<

The opposite to Sweden were it allway rains...
And yes you can expect the tires to last for 12,000+ I had my last set of Corsa tires for 15,000 miles including 2~3 track days.

EDITED. I keep telling you guys that ESP is never fully OFF. Only the traction control...
Part of the ESP gets switched OFF.
As soon as brakes are applied the ESP (stability program) comes back ON to baby sit you and your car even if the switch was selected OFF. Without warning from the system you will get differential braking to "stabilize" the car.
The only way to completely disable ESP is to pull the fuse out but doing so also kills the ABS and worst kills the EBD which in return will guaranty you premature rear brake lock up.
BTW, EDL is always active regardless of ESP switch position. That means that the EDL traction control <b>cannot</b> be deactivated.
It does deactivate automatically above 50 mph or if its algorithm feels the brakes are overheating. Again by pulling the ABS fuse you will deactivate the EDL but with the same results as above.
